What does the greek god Demeter need to survive?

Demeter, the Greek goddess of agriculture and the harvest, fundamentally depends on the fertility of the earth and the changing seasons for her survival. Her well-being is closely tied to the growth of crops, as she governs the harvest and the nurturing of the land. Additionally, her emotional state is linked to her daughter Persephone; when Persephone is with her, the earth flourishes, but when she is in the Underworld, Demeter experiences grief, leading to barren seasons. Thus, a harmonious balance between the earth's productivity and her relationship with Persephone is essential for Demeter's vitality.
